The Horn of Africa is experiencing an outbreak of wild poliovirus type 1 (WPV1). Six cases have been confirmed, four from Somalia (Banadir and Bay region) and two from Kenya (Dadaab in north-‐eastern Kenya). The first case was confirmed in Somalia on 9 May 2013 and in Kenya on 22 May. This is the first outbreak in Somalia since 2007 and in Kenya since 2011. Outbreak campaigns have been launched in both countries. Immunization campaigns are planned and being conducted in neighboring Ethiopia and Yemen to boost population immunity levels and minimize the risk of spread of the outbreak.
